visual c++ - CStatic not receiving WM_CTLCOLOR -

i think missing small here.

i trying make class inherits cstatic transparent background. have managed create instance of class , displayed in parent cview. when add onctlcolor message handler going through class view on visual studio make background transparent, never fires.

here code snippet:

foo.h

class foo: public cstatic {     declare_dynamic(foo)  public:     foo();     virtual ~foo();     virtual void createctrl(cwnd * parent, point topleft, size sz);  protected:     declare_message_map() public:      afx_msg hbrush ctlcolor(cdc* pdc, uint nctlcolor);     afx_msg bool onerasebkgnd(cdc* pdc); }; 

foo.cpp

void foo::createctrl(cwnd * parent, point topleft, size sz) {     crect rect(topleft, sz);     create(pitem->value->getbuffer(), ws_child | ws_visible | ss_center | ss_notify, rect, parent);     showwindow(sw_show); }  begin_message_map(foo, cstatic)      on_wm_ctlcolor_reflect()     on_wm_erasebkgnd() end_message_map()  hbrush foo::ctlcolor(cdc* pdc, uint nctlcolor) {     pdc->setbkmode(transparent);     return (hbrush)getstockobject(null_brush); }  bool foo::onerasebkgnd(cdc* pdc) {     return false; } 

can suggest might doing wrong?

wm_ctlcolor sent parent window, not static control.

to catch message in static control class, need use on_wm_ctlcolor_reflect in message map, see msdn docs , use hbrush foo::ctlcolor(cdc* pdc, uint nctlcolor).
